Overview of Colorado State Income Tax for 2015

Before you dive into filing your Colorado tax return, it’s essential to understand the basics of the state’s income tax system for the 2015 tax year. Like other states, Colorado has specific requirements for who needs to file and what taxable income is. Below is an overview of the filing requirements, income thresholds, key deadlines, and changes from the prior year.

Who Needs to File?

In Colorado, most residents who earned income during the tax year must file a state income tax return. This includes individuals, sole proprietors, and small business owners. However, there are income thresholds that determine whether you need to file.

For the 2015 tax year:

  • Single filers: You must file if your gross income was at least $12,000.
  • Married filing jointly: You need to file if your combined income was
  • Head of household: The threshold is $18,000 for filing.

These figures are for individuals under the age of 65. If you’re 65 or older, the thresholds may vary slightly, so check the official guidelines to ensure you meet the requirements.

Income Tax Deadlines

The deadline for filing your 2015 Colorado tax return was April 18, 2016. If you missed the deadline, you may face penalties and interest charges, but you still have options to file late or request an extension.

Key Changes from 2014 to 2015

For 2015, there were a few critical updates to Colorado’s tax system:

  • Personal exemptions and deductions: A slight increase in the personal exemption can reduce your taxable income.
  • Sales tax changes: Colorado adjusted its sales tax rates in certain regions, which could impact business deductions.
  • Standard deduction updates: The state increased the standard deduction slightly, providing some relief to taxpayers.

These changes were designed to simplify the process for most taxpayers. Consider them as you file your taxes.

What Forms to Use for Your Colorado Tax Return

Filing your Colorado tax return requires the correct forms, which can vary based on your income and any deductions or credits you claim. Below is a guide to help you navigate the necessary forms for the 2015 tax year.

Main Colorado Income Tax Form (Form 104)

For most individual taxpayers, the primary form for filing their Colorado tax return is Form 104, also known as the Colorado Individual Income Tax Return. This form reports your total income, claims deductions and credits, and determines your tax liability.

Form 104 is relatively simple to complete, but you’ll need your W-2, 1099, and other income documentation to complete it correctly.

Common Schedules

  • Schedule A – Itemized Deductions: If you itemize deductions instead of taking the standard deduction, you must complete Schedule A. This includes deductions for mortgage interest, property taxes, and charitable donations.
  • Schedule CR – Credits: Colorado offers a variety of credits, including the Earned Income Tax Credit (EITC), Child Tax Credit, and Education Credits. You must complete Schedule CR and attach it to Form 104 to claim these. These credits can help reduce your overall tax liability.

Additional Forms for Business Owners

If you're a small business owner or sole proprietor, you may need additional forms, such as

  • Form 106: Used by corporations for filing their Colorado corporate income tax returns.
  • Schedule C: For reporting business income and expenses for sole proprietors.

Where to Find Forms

You can find all the forms you must file on the official Colorado Department of Revenue website or their Revenue Online system. Simply visit the website and select "Tax Forms" to access a list of all the available forms.

For your convenience, here are a few direct links:

  • Form 104 – Colorado Individual Income Tax Return
  • Schedule A – Itemized Deductions
  • Schedule CR – Credits

Tax Credits and Deductions

Don't forget that Colorado offers several tax credits and deductions that can lower your tax liability:

  • Earned Income Tax Credit (EITC): Available for low-to-moderate-income individuals and families.
  • Child Tax Credit: A credit available to those with dependent children.
  • Education Credits: For qualifying tuition and education expenses.

Be sure to review these options to make sure you claim all eligible credits and deductions.

Step-by-Step Instructions to Complete Your Return

Completing your Colorado tax return can seem overwhelming, but breaking it down into manageable steps makes the process much easier. Below is a detailed, step-by-step guide to help you correctly fill out your 2015 Colorado tax return.

Step 1: Gather Required Documents

Before you begin, ensure you have all the necessary documents. This includes:

  • W-2 forms from your employer(s) to report wages.
  • 1099 forms for any other income, such as freelance or investment income.
  • Receipts and records of deductions, such as mortgage interest, property taxes, and charitable contributions, if you're itemizing.
  • Records of any education-related expenses for claiming education credits.

Having these documents ready will make the process much smoother.

Step 2: Fill Out Form 104

Start by filling out Form 104:

  • Personal Information: Enter your name, Social Security number, and filing status (single, married filing jointly, etc.).
  • Income: Add your total income from W-2s, 1099s, and any other sources of revenue. Be sure to include all taxable income, such as interest, dividends, and business income.
  • Adjustments to Income: If applicable, include any adjustments to your income (e.g., IRA contributions or student loan interest deductions).

Step 3: Claim Deductions and Credits

Once your income is reported, the next step is claiming deductions and credits. Colorado allows both standard deductions and itemized deductions (via Schedule A).

  • Standard Deduction: If you choose the standard deduction, you can skip Schedule A and proceed to the next section.
  • Itemized Deductions (Schedule A): If you have significant deductible expenses, such as mortgage interest, medical expenses, or charitable donations, it may benefit you to itemize your deductions. Fill out Schedule A and attach it to your Form 104.
  • Tax Credits: Colorado offers several credits that can reduce your tax liability. Be sure to fill out Schedule CR for credits like the Earned Income Tax Credit, Child Tax Credit, and Education Credits. These credits directly reduce the amount of tax you owe.

Step 4: Review Your Calculations

Review your calculations once you've filled in the income, deductions, and credits to ensure everything adds up. Double-check the following:

  • Income: Ensure all income is reported and correctly calculated.
  • Deductions and Credits: Verify that you've claimed all eligible deductions and credits.
  • Math: Make sure your addition and subtraction are accurate.

Common mistakes to avoid include forgetting to include all income (especially 1099 income), not claiming all eligible credits, or missing deductions like charitable contributions.

Step 5: Determine Your Tax Liability or Refund

After completing Form 104 and all necessary schedules, calculate whether you owe taxes or are entitled to a refund:

  • If you owe taxes: You'll need to make arrangements for payment (explained in the next section).
  • If you're due a refund, choose how you want to receive it, whether by check or direct deposit.

Step 6: Sign and Date Your Return

Once you've completed the form, don’t forget to sign and date it! If you're filing jointly, both spouses must sign. If you are e-filing, the system will prompt you to sign the return electronically.

How to File Your Colorado Tax Return

Once you’ve completed your Colorado tax return, the next step is filing it with the Colorado Department of Revenue. There are two primary filing methods: e-filing and paper filing. Below, we’ll explain both options so you can choose the one that best suits your needs.

Option 1: E-Filing Your Tax Return

The easiest and fastest way to file your Colorado tax return is through e-filing. This option is available through Revenue Online, the Colorado Department of Revenue’s secure online portal. E-filing offers several benefits:

  • Faster processing: E-filing is usually processed much quickly than paper filing.
  • Direct deposit: If you’re due a refund, you can opt for direct deposit, which typically takes less time than receiving a check.
  • Accuracy: E-filing helps reduce errors since the system checks your entries for mistakes before you submit.

To e-file, follow these steps:

  1. Visit the official Revenue Online website (https://www.colorado.gov/pacific/tax/revenue-online).
  2. Log in or create an account if you don’t already have one.
  3. Follow the instructions to file your Colorado tax return electronically.
  4. Choose your preferred method of payment or refund (check or direct deposit).

Option 2: Paper Filing Your Tax Return

If you prefer to file your tax return on paper, you can mail your completed Form 104 and any attached schedules to the Colorado Department of Revenue. Here’s how to do it:

  • If you owe taxes: Mail your return with payment to the following address:
    • With Payment: Colorado Department of Revenue, PO Box 17087, Denver, CO 80217-0087.
  • If you don’t owe taxes or are due a refund: Mail your return to this address:
    • Without Payment: Colorado Department of Revenue, PO Box 17087, Denver, CO 80217-0087.
  • Zero balance: If your tax return shows a zero balance, simply mail your completed Form 104 to the same address without including a payment.

Essential Notes on Paper Filing

  • Timeliness: If you’re filing by paper, send it before the deadline to avoid penalties and interest. Remember, the 2015 tax year deadline was April 18, 2016.
  • Double-check your address: Always use the correct address when mailing your return. Incorrect addresses can delay your processing or result in your return being lost.

Why Consider E-Filing Over Paper Filing?

While paper filing is an option, e-filing offers several key advantages, including faster processing times, fewer errors, and quicker refunds. If you are wondering whether e-filing is the right choice, it is also a more secure method for filing your income tax return.

How to Make a Payment

Several payment options are available if you owe taxes after filing your Colorado tax return. Making your payment on time is essential to avoid penalties and interest. Below, we outline the different ways you can pay your taxes, along with important deadlines and details to remember.

Payment Methods for Colorado Taxes

There are multiple ways to make your payment for Colorado taxes:

Online Payment Portal

The official Revenue Online system is the easiest and most convenient payment method. You can pay using a debit card, credit card, or ACH transfer from your bank account.

  • Visit the Revenue Online website (https://www.colorado.gov/pacific/tax/revenue-online) and select “Make a Payment” to start.
  • Choose your preferred payment method, complete the details, and submit your payment.

Credit Card

You can use your credit card to pay taxes online through the official payment system. However, a processing fee may apply when using a credit card.

  • Check the Revenue Online website for details about processing fees.

Check or Money Order

If you prefer to pay by check or money order, make your payment payable to the Colorado Department of Revenue. Include your name, Social Security number, and the tax year (2015) on your payment.

  • Mailing Address for payments:
  • Colorado Department of Revenue, PO Box 17087, Denver, CO 80217-0087.

Payment Deadlines and Penalties

You must make your payment by the deadline to avoid late fees. For the 2015 tax year, the deadline for filing and paying your taxes was April 18, 2016. If you miss the deadline, you will likely incur interest and penalties on the amount owed.

  • Interest: Interest is charged daily on unpaid taxes, starting from the original due date.
  • Penalties: The penalty for late filing is 5% of the unpaid tax for each month it is late, up to a maximum of 25%.

Payment Plans and Extensions

Colorado offers payment plans if you can’t afford to pay your full tax liability at once. You can apply for a payment plan through the Revenue Online portal.

If you cannot pay by the filing deadline, filing an extension can allow you extra time to submit your tax return, but it does not extend the payment time. You must still pay any taxes owed by the original due date to avoid interest and penalties.

How to Track Your Refund or Balance Due

Once you've filed your Colorado tax return, one of the most important things you’ll want to know is whether you’ll receive a refund or owe taxes. Fortunately, the state provides easy ways to track the status of your refund or check how much you owe.

Tracking Your Refund

If you expect a refund, you can track its status using the official Revenue Online tool. Here’s how:

  1. Visit the Revenue Online website (https://www.colorado.gov/pacific/tax/revenue-online).
  2. Log in with your account details.
  3. Select the "Check My Refund Status" option to view where your refund is being processed.

The refund process typically takes 2 to 3 weeks if you e-file and choose direct deposit. Paper returns may take a bit longer.

How to Track Your Balance Due

If you owe taxes, you can also check the status of your balance due. After logging into Revenue Online, you can select "View My Account" to see how much you owe, including any interest or penalties that may have accumulated. This feature also allows you to make payments directly through the site.

Essential Notes on Refund and Balance Due Status

  • Processing time: E-filed returns usually process faster than paper returns. Interest on any overdue taxes begins accruing the day after the due date, so it’s essential to check and pay any balance due as soon as possible.
  • Payment plans: If you cannot pay the full amount, you can set up a payment plan through Revenue Online. This allows you to pay in installments while avoiding more severe penalties.

By staying on top of your refund or balance due status, you’ll avoid unnecessary interest or penalties and ensure your tax responsibilities are handled efficiently.

Final Filing Checklist

Before you submit your Colorado tax return, you must go through a final checklist to ensure everything is in order. This simple step will help you avoid costly mistakes, penalties, or delays. Here's a comprehensive list of things to check before you file your 2015 Colorado tax return.

Final Filing Checklist

  • Completed Tax Return: Make sure all sections of your Form 104 are filled out completely and accurately.
  • W-2s and 1099s: Double-check that you’ve included all income documentation, such as your W-2 from your employer and any 1099 forms for freelance work or investment income.
  • Schedules and Credit Forms: Ensure you’ve completed and attached any necessary schedules (like Schedule A for itemized deductions) and credit forms (such as Schedule CR for the Earned Income Tax Credit or Child Tax Credit).
  • Payment or Refund Method Selected: Verify how you want to receive your refund (check or direct deposit) or how you intend to pay if you owe taxes.
  • Correct Mailing Address: If you are filing by paper, ensure your mailing address is accurate to avoid delays.
  • Copies Saved for Your Records: Keep copies of your completed return, schedules, W-2s, and other supporting documents for your records. They’re essential in case of future audits or inquiries.

Taking the time to go through this checklist before submitting your return will help ensure that your filing goes smoothly and without issues.
